Did this quick map of the intersection.

It's a main road so I feel I had right of way as he was at a stop sign crossing a busy 2 lane road, I got the the intersection just as he was about to cross the road so was stopped. I know it's a pain to cross there as I almost never use it, just easier to got the the near by roundabout and use it to get the the servers station. Which BTW he pulled into after cutting me off.
After what happened 2 months ago and the scary stuff on YouTube I've learnt to be more tolerant of stupid drivers.
So who has the right of way?
Am I the stupid driver this time?
FYI I do have video of the incident I can post later.
